Bradley, Charlotte, N. 0. Application February 4, 1946, Serial No. 645,259 Claims. (01. 46-7) This inventionrelates to a bubbleforming device and more especially to a member having a reservoir and an annular portion associated therewith with means ble forming solution can flow slowly from the reservoir to the annular member, and said annular member having associated therewith a pivoted wiper which, when the bubble forming device is waved in the air, and given a turn of approximately .180 degreesbefore it is waved the opposite direction, the wiping member will oscillate on its pivot from one side of the annular member to the other todeposit a film on the annular member. The'turning'of the bubble forming device occurs at each end of the swing of the operator so as to new film on the annular member'to formfbubbles as the bubble forming device is -swung in the opposite direction.

It is'fanobjectpf this invention to provide a bubble forming device comprising a reservoir serving as a handle and an annular member assoclated therewith, whereby a quantity of bubble forming solution can be stored in the handle reservoir with one or more openings whereby the fiow outwardly onto ber.= I

' It is another object of this invention to provide a bubble forming device comprising a handle member having a reservoir therein for holding a an annular member associated with the handle reservoir, with thehandle reservoir having one stated, other'objects will appear as the descriptionproceeds when taken in connection with the "accompanying drawings, I Figure in which m 1 is a top plan view of a bubble forming in Figure 1;

Figure 8 is a. longitudinalsectional view taken substantially along the line 8-8 in Figure 7;

Figure 9 is a cross sectional view taken along the line 9-9 in Figure 7;

Figure '10 is a, top plan view of the structure as shown in Figure 7 on a smaller scale so as to show the entire handle member associated therewith.

Referring more specifically to the drawings, the numeral I0 indicates a substantially cylindrical member closed at its left hand end and open at its right hand end and having threadably mounted therein a closure II, the members I0 and I I forming a reservoir I2 for the storage of a bubble forming solution.

'Integral with the closure II is a, sheet-like member I3 having a circular opening I4 therein, and also having a transverse hole I5 in whichis pivotally mounted the free ends of a U-shaped member I6, said free end having projections I1, and I8 integral therewith which project into the hole I5 in a loose manner so as to allow swinging movement of the member I5, which is termed a wiper, for depositing a bubble forming solution in the form of a film across the opening I4 in the member I3. i

The closure member II has one or more openings I8 through which the bubble forming solution contained in reservoir I2 may flow out onto the member I3 so that it can be deposited in the form of a film over the circular opening I 4 when the wiper I 6 is caused to pass across the opening 4 from one side to the other by a swinging movement of the entire device, the limit of the swing being substantially as shown in dotted lines in the lower right hand portion of Figure 1. I

Figures 4, 5 and 6 show a modified form of the has one end thereof closed by a suitable closure such as a stopper 2|. This member 20 is hollow, thus forming a reservoir 22 for a bubble forming solution. The right member 24, having a circular opening 25 therein. The member 24, if desired, can be secured tightly portion are not in contact in the flattened portion 23 by means of rivets 26. This shank portion of member 24 is slotted as at 21 for the entire distance of the portion disposed within the portion 23 of the handle reservoir member 20. This slot 21 extends slightly beyond the end of flattened portion 23. In this exposed portion of the slot are adapted to be loosely secured the inturned ends of a wiper member 28 which is adapted to swing onthe in turned endsas a pivot from one side ofthe annular member to the other to completely cross the circular opening 25 to deposit a film of the bubble forming solution across the opening 25. One of the positions assumed by the, swinging of the wiper 28 is shown in dotted lines in Figure 3, and it is evident that this will swing to the other side of and beyond the opening 25 in the same manner.

In Figures '7 to 10, inclusive, still another modified form of the invention is shown in which a cylindrical member 3% serves as a handle and as a storage reservoin-it being hollow and providing a storage'reservoi 3| within the member 30. The left hand end of this-cylindrical mem her is adapted to .be permanently or temporarily closed by a stopper 32, this stopper 32 being preferably gluedor otherwise fixedly secure therein, although if desired, it.;could be removed for refilling; but I prefer to;prov ide .a suitable opening near the other end of the member 33 in which a an suitable stopper 33 isdisposed which can be removed for refilling the reservoir 31 Fixedly -se cured in stopper 32 is an extended rodorlother member 34 which can, if desired, have a handle member 35eon, its free end whereby greater le- 35 verage can be obtainedini a swinging movement than from the "forms shown in Figures 1 to 6, in-

elusive. Y g V v The member 39- is flattened at its right hand end in the drawings as at 36 and hasa circular 4 opening 31 therein which is adapted to be traversed by a U-shaped wiper 3B havingits free end open and having its medial portion loosely penetrating an opening 39 in thebase of the flattened portion 36, At ;.the point where this a opening 39 penetrates the flattened, portion 36, the upper and lower portions ,of. this flattened witheach other, thus leaving a small gopening 40 through which. the bubble forming solut'on may flow into the openso ing 39 and outwardly ontothewiper 38 and onto the flattened portion 36 so thatfby swinging of the wiper38 from one dotted line position to. the other as shown in Figure 7, the bubble'forming solution will be deposited in the form of a film as over the opening 31. r In all forms of this invention, Ihave shown thehandle reservoir portion as being circular in cross section, butof course, it. could .be iniany desired shape; that is, it could be oval in cross so section or,square incrossssection orally. desired shape without departing :from

invention.

The material used 'inthe construction of this device can be of any desired type, such as plastic, as hard rubber, sheet metal, or. any othersuitable material. Q I

In the drawings,.the wiper members 16, 28, and 38 are shown as having a-slight-clearance between their associated .mernbers having the openings I4, 25, and-.31 therein; -.It is evident that, inoperation, one. or the other leg of the the spirit of the wiper will be in slidingcontact with the: member hav n thgopening: therein, s'o as to'deposit a fllni across the opening.

.degrees before the swing deposited by "the wiper theopening therein'and forming a film across ployed, they are used bubble forming solution in "associated :solution, said handle In all forms of the invention, the openings are shown as circular. It is evident that any desired shape of opening may be employed as it is not necessary that the openings be circular for the, proper formation of bubbles.

In operation, with the reservoir having the bubble forming solution therein, the wiper arm is disposed on one side or the other of the apparatus, or in one of the dotted line positions shown in the drawings, after it has been thrown across the opening to deposit a film thereover. The apparatus is then swung through the air and a plurality of bubbles are formed by the air passing through the opening. At the end of the swing, the entire apparatus is rotated axially, substantially through one hundred and eighty is started in the other direction. The turning of the bubble forming device substantially one hundred and eighty degrees is accomplished just before the end of a swinging-operation so as to cause the wiper arm to move to the other side and pass across the opening to deposit a film thereonto at which time the apparatus is swung in the reverse direction to ,cause air to pass through the opening'thus to form a plurality of bubbles. This operation is repeatedback and forth as long as" desired, it not being necessary to dip the portion having the opening therein into a jar of bubble formin solution as the solution is. applied constantly to the exterior of the portion having the opening therein where it is'readil'y available for .being onto that portion having the opening.

in the drawings and specification there has been set forth a preferred embodiment ofthe invention, and although specific terms are emin a generic and descrip- 0 tivesense only, and not for .purposes of limitation,

the scopefl'of the. invention being defined in the claims. f
